北京地区八、九月蔬菜淡季是生产上的一个突出问题。夏茄子的播种面积约占夏播蔬菜面积的25—50%,总产约占夏播蔬菜总产的20—25%。由于每年气象条件的变化,夏茄子的单产很不稳定,研究夏茄子产量与气象条件的关系,可以为充分利用有利的气象条件,避开气象灾害,夺取夏茄子的高产稳产提供科学依据。一、夏茄子单产变化情况根据北京市近郊(包括朝阳区、海淀区、丰台区、石景山区、国营农场)和一些社、队夏茄子调查材料绘制成图1,从中可以看出单产
Beijing August and September vegetable off-season is a prominent issue in production. The sowing area of summer eggplant accounts for about 25-50% of the summer sowing vegetable area, and the total output accounts for about 20-25% of the summer sowing vegetable output. Due to the annual changes in weather conditions, summer eggplant yield is very unstable, the study of summer eggplant yield and weather conditions, can make full use of favorable weather conditions, avoiding meteorological disasters, to obtain high yield and stability of summer eggplant to provide a scientific basis. First, the changes in the yield of summer eggplant According to Beijing suburbs (including Chaoyang District, Haidian District, Fengtai District, Shijingshan District, state-owned farms) and some clubs, summer squash survey material drawn into Figure 1, we can see that the yield
